B) synthetic reactions. There is no such thing as "synthetic reactions" but synthesis reactions.
Mass of water is 11.52 grams.
Overall chemical equation for reaction of combustion a compound containing only carbon and hydrogen:
CxHy + O₂ → xCO₂ + y/2H₂O
m(CxHy) = 7.02 g; mass of the compound
m(O₂) = 25.5 g; mass of oxygen
m(CO₂) = 21.0 g; mass of carbon dioxide
m(H₂O) = ?; mass of water
Conservation of matter states that the mass of the reactants have to be equal to the mass of the products.
m(CxHy) + m(O₂) = m(CO₂) + m(H₂O)
7.02 g + 25.5 g = 21.0 g + m(H₂O)
m(H₂O) = 32.52 g - 21.0 g
m(H₂O) = 11.52 g; mass of water

It would be that the cornea is not curved enough, thus not allowing the pupil to expand to perceive further distances clearly. :)
Answer;
-Prohibited from use by OSHA
Explanation;
-Carbon tetrachloride is a clear and colorless liquid with an odor similar to that of chloroform.It is employed as a chemical reagent for a number of purposes, as a raw material in chemical manufacture and is, used very widely as a reagent to extinguish fires.
-It volatizes very easily, is a non-conductor of electricity and, as noted above, freezes at very low temperatures.
-It is effective, due to the blanketing effect of its vaporized fumes, on many Class B or volatile, flammable liquid fires and because it will mix with certain volatile, flammable liquids and form a non-burning combination.
